Controller box ports

Zada Tech’s controller box acts as the heart of your multigauge. All the sensors, including the OBDII hardware, collect the data from your car and output as various graphical gauges via an HDMI output.

There are various ports on the controller box, these include:
• Power port

• Sensor ports
• Joystick and headlight switch ports
• HDMI port
• OBDII port
• USB port

Power port (IGN 12V)

This is the power point for the controller box. It connects to your car’s ignition or ACC switch. Please note this is independent from the LCD power.

Sensor ports

If you have any of the Zada Tech sensors they could be connected to the ports shown below. Please refer to the ‘Sensors’ section of the guide on the wiring of the sensors.

Joystick ports, headlight switch ports & HDMI port

The rotary joystick that comes with the kit connects to the JOYSTICK port. Please refer to the ‘Joystick’ section of the guide on how to connect the joystick.

LIGHT SWITCH port connects to your car’s main headlight switch and the LCD backlight. Please refer to the ‘Headlight switch’ section of the guide on how to wire this port to your car and the LCD.

HDMI port outputs the graphical gauges to the LCD.

AFR (Air Fuel Ratio)

This AFR single port is used to connect and input a wideband controller signal. If you already have an external Air Fuel Ratio wideband sensor controller, such as the one Zada Tech supplies or the lines of AEM or Innovate, you can connect the output from these controllers to this port. The signal that this port accepts is 0-5 volts.

AIR FUEL RATIO ports

You may have chosen to have Zada Tech’s Air Fuel Ratio wideband controller integrated into your controller box. In this case the ‘AFR’ single port is redundant and instead you will have 6 dedicated ports ‘AIR FUEL RATIO’ to connect the wideband sensor into. The sensor normally comes with a 6 wire connector. Each wire is marked with dots indicating which port, on the controller box, it belongs to. The connector comes pre-wired, however it needs to be extended. Please make a note of which wire is which with the indicated dots while extending them.

Joystick

The rotary joystick supplied with the kit comes with 4 marked wires. The wires are marked as BLUE, YELLOW, RED and BLACK.

The wiring for the joystick is as follows:

1 BLUE
2 YELLOW
3 RED
4 BLACK

If LEFT & RIGHT function does not perform correctly, swap BLUE (1) and YELLOW (2) wires.

Headlight switch

The kit is equipped with night mode for the LCD. This gets activated, and in turn dims the LCD, when the main headlights are turned on.

The ‘LIGHT SWITCH’ port needs a 12 volts feed from your main headlight switch into the ‘IN’ single port. The ‘IN’ single port should connect to the blue wire from the LCD itself.

LCD

The LCD is powered independently to the controller box. It needs a 12v supply. LCD is powered with your car’s ignition or ACC.

The wiring for the power is as follows:

Red +12v (IGNITION or ACC)
Black - (GROUND)

The blue wire from the LCD should connect to the ‘LIGHT SWITCH (OUT)’ single port.

The LCD should connect to the controller box via the supplied HDMI cable. Please connect the cable to the HDMI port on the LCD and the controller box.

OBDII

This kit is equipped with a CAN bus OBDII reader. Connect the OBDII cable that comes supplied with your kit to the controller box then to your car’s OBDII port. The OBDII port is normally found under the steering column and above the pedals. The location can differ from one car manufacturer to another.

Reverse Camera

The LCD supplied with the kit also comes with an AV input. This is suitable for a reverse camera.

To connect a reverse camera, plug the AV cable from your reverse camera to the yellow round AV input jack. Additionally connect the GREY wire from the LCD to your reverse light. The GREY wire tells the LCD to switch channels to the AV channel when a signal is received from the reverse lights. Going out of the reverse gear will put the LCD into the HDMI channel again and you will see your wonderful gauges.
